Bought for my new home, as previous owner had espresso bar. This machine is just a little too much for my wife. We’re going to a more “push” button espresso machine so we both can enjoy the process. I built it out with walnut wood and it’s a beautiful machine. I had it plumbed in but still have all the pieces to return it to a tank system. Here’s the description and photos. Marzocco's GS3 Espresso Machine is designed for passionate, avid espresso enthusiasts who know that investing in one of the best machines available is the only way they'll ever be satisfied. The GS3 is pricey, but its commercial-grade features more than balance the cost: Dual stainless steel boilers, powerful steaming functionality, PID temperature control, volumetric pump and variable hot water temperature regulation — to name a few.
